Usage

What does outpatient mean? Outpatient is commonly used as an adjective to describe treatment that does not require a patient to stay overnight at a hospital or other care facility—they come and leave on the same day.Outpatient is used in contrast with the term inpatient, which describes treatment that requires a patient to be admitted for at least one night.The terms are especially used in phrases like outpatient procedure (after which the patient can leave, instead of staying for further observation or treatment), inpatient treatment (which requires the patient to stay overnight at the hospital), and inpatient room (where such patients stay).Outpatient and inpatient are typically used in the context of hospitals, though inpatient can also refer to a patient who is admitted overnight at a mental health facility or other kind of clinic.Both terms can also be used as nouns referring to such patients.Example: I have an outpatient procedure scheduled for tomorrow morning, so I should be back home by the afternoon.
